The new general, Metellus, was not one to be sent under the yoke. He defeated Jugurtha in the field and pursued him so unrelentingly that soon the African usurper was a fugitive, without an army, and with only some fortresses under his control.
Metellus had with him as his principal officer a man who was to become famous in Roman history. This man, Caius Marius, was then fifty years of age. Yet he had years enough before him to play a mighty part. He was a man of the people, rough and uneducated; scorned learning, but had a vigorous ambition and a striking military genius. He claimed to be a New Man, knew no Greek, and boasted that he had no images but "prizes won by valor and scars upon his breast."
This man made himself the favorite of the populace, was elected consul, and by undisguised trickery took the conduct of the war out of the hands of Metellus just as the latter was about to succeed. With him to Africa went another man who was to become equally famous, L. Cornelius Sulla, the future chief of Rome. Sulla was not a New Man. He was an aristocrat, knew Greek better than Marius knew Latin, was educated and dissipated, and showed the marks of a dissolute life in his face. When he rode into the camp of Marius at the head of the cavalry he had seen no service, and the rugged soldier looked with contempt on this effeminate pleasure-seeker who had been sent as his lieutenant. He soon learned his mistake, and before the campaign ended Sulla was his most trusted officer and chief adviser.
In the subsequent conduct of the war there is an interesting story to tell. There were two hill-forts in Numidia which still remained in Jugurtha's control. One of these was taken easily. The other—which contained all that was left of the usurper's treasures—was a formidable place, which long defied the Roman engineers. It stood on a precipitous rock, with only a single narrow ascent; was well garrisoned and supplied with arms, food, and water; and so long defied all the efforts of Marius that he almost despaired of its capture.
In this dilemma a happy chance came to his aid. A Ligurian soldier, a practised mountaineer, being in search of water, saw a number of snails crawling up the rock in the rear of the castle. These were a favorite food with him, and he gathered what he saw, and climbed the cliff in search of more. Higher and higher he went, till he had nearly reached the summit of the rock. Here he found himself near a large oak, which had rooted itself in the rock crevices, and grew upward so as to overtop the castle hill.
The Ligurian, led by curiosity, climbed the tree, and gained a point from which he could see the castle, undefended on this side, and without sentinels. Having taken a close observation, he descended, carefully examining every point as he went. He now hastened to the tent of Marius, recounted to him his exploit, and offered to guide a party up the perilous ascent.
Marius was quick to seize this hopeful chance. Five trumpeters and four centurions were selected, who were placed under the leadership of the mountaineer. Laying aside all clothing and arms that would obstruct them, they followed the Ligurian up the rock. He, an alert and skilful climber, here and there tied ropes to projecting points, here lent them the aid of his hand, here sent them up ahead and carried their arms after them. At length, with great toil and risk, they reached the summit, and found the castle at this point undefended and unwatched, the Numidians being all on the opposite side.
Marius, being apprised of their success, ordered a vigorous assault in front. The garrison rushed to the defence of their outer works. In the heat of the action a sudden clangor of trumpets was heard in their rear. This unexpected sound spread instant alarm. The women and children who had come out to watch the contest fled in terror. The soldiers nearest the walls followed. At length the whole body, stricken suddenly with panic, took to flight, followed in hot pursuit by their foes.
Over the deserted works the Romans clambered, into the castle they burst, all who opposed them were cut down, and in a short time the place which had so long defied them was theirs, while the four trumpets to which their victory was due sounded loudly the war-peal of triumph.
Jugurtha was still at large. He was supported by Bocchus, king of Mauritania, whose daughter he had married. Sulla was sent to demand his surrender. Bocchus refused at first, but at length, through fear of Rome, consented, and the bold usurper was betrayed into Sulla's hands.
